Disperse Dyes

 

a group of poorly water-soluble dyes used for dyeing polyamide, polyester, polyacrylonitrile, and acetate fibers. Disperse dyes are characterized by the absence of the SO3H and COOH acid groups and a molecular weight of no more than 350. Disperse dyes are dispersed during their manufacture down to a particle size of 0.2-2.0 microns.

In order to increase the amount of colors and maintain the color fastness to light, washing or high temperature of the textiles, an extensive amount of research has been conducted to improve the limited swelling of fibers with the help of special dyeing auxiliaries such as carriers (e.g., acetophenone, methyl benzoate) or swelling agents containing dimethyl formamide, dimethyl sulfoxide and so on, which contribute to the ability of cationic dyes or disperse dyes to enter the internal space of the fibers [9-11].
